Giovanni van Bronckhorst believes Liverpool are difficult to play against because their "playing style is direct with long balls".
The Reds take on Champions League rivals Rangers at Ibrox on Wednesday night. The Scottish giants are after their maiden points of the tournament after losing their first three fixtures to Napoli, Ajax and Liverpool - suffering a 2-0 loss at Anfield last week.
Liverpool, meanwhile, are hoping to take another step towards the knockout stages of the Champions League in Glasgow. Last season's finalists picked up six points from their first three outings, despite suffering a humbling 4-1 defeat to Napoli in Italy.
